| Abstract | Joint transmitter and receiver beamforming algorithms for uplink multiuser multi-input multi-output (MIMO) communication systems are proposed in this paper based on maximizing an utility function, which is defined based on the difference between desired signal power and interference plus noise power. Two iterative beamforming algorithms are developed by maximizing the utility function of each user via parallel and serial methods. In parallel method, the transmitter and receiver beamforming vectors of each user are iteratively updated by maximizing its utility function. However in serial method, at first step, the transmitter beamforming vectors of all users are iteratively updated by maximizing the utility function of each user and then receiver beamforming vectors of users are calculated. By computer simulations, the performances of the proposed beamforming algorithms are evaluated and also compared with the performance of the duality method (DM) based beamforming algorithm. With respect to bit error rate (BER) and convergence rate, the results show that the new proposed beamforming algorithms have superior performances in comparison with the DM based beamforming algorithm. Also, for some cases, the serial method achieves better performances in comparison with the parallel method. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
